How much work (in kJ/hour) is generated by the first turbine, which is 80% efficient? b. How much work (in kJ/hour) is generated by the second turbine, which is 80% efficient? c. Steam for the turbines is generated by a boiler. How much heat must be supplied to the boiler (not shown), which has 300 kg/hour of flow? The stream entering the boiler is T = 170oC and P = 8 MPa. The stream exiting the boiler matches the inlet to the first turbine.

Steam is used in the following turbine system to generate electricity:
